Abstract
The computer-implemented method for glass bending includes obtaining a deviation of a real shape of a glass from a desired shape of the glass, the glass is produced by a glass bending process; determining a variation of at least one parameter associated with the glass bending process, at least in part based on the deviation of the real shape from the desired shape; and adjusting the at least one parameter based on the variation for compensation of the deviation.
Claims9
A computer-implemented method for glass bending comprising:
- obtaining a deviation of a real shape of a glass from a desired shape of the glass, the glass is produced by a glass bending process;
- determining a variation of at least one parameter associated with the glass bending process, at least in part based on the deviation of the real shape from the desired shape;
- and
- adjusting the at least one parameter based on the variation for compensation of the deviation,
- wherein determining the variation comprises
- determining an effect of the at least one parameter on the deviation by decoupling a contribution of the at least one parameter to the deviation from a contribution of one or more further parameters associated with the glass bending process to the deviation, and
- determining the variation based on the deviation and the effect of the at least one parameter,
- wherein the glass bending process comprises applying a mold on the glass, and wherein the effect of the at least one parameter on the deviation is determined based on following variables:
- reference positions used in measuring the deviation, slopes of a surface of the mold at the reference positions, measurement positions used in measuring the deviation, and slopes of the surface of the mold at the measurement positions;
- or
- wherein the glass bending process comprises a roller bending process, and the effect of the at least one parameter on the deviation is determined based on following variables:
- a primary radius of the glass, reference positions used in measuring the deviation, measurement positions used in measuring the deviation, and a secondary radius of rollers in the roller bending process;
- or
- wherein the glass bending process comprises a roller bending process, and the effect of the at least one parameter on the deviation is determined based only on following variables:
- a primary radius of the glass, reference positions used in measuring the deviation, and measurement positions used in measuring the deviation.
